Wikipedia: Land of opportunity
The land of opportunity is a phrase used to suggest that a place presents many possibilities for people to earn a prosperous living, and succeed in their economic or social objectives.

It is often used with reference to the United States of America, and is similar to the concept of the “American dream”. It became popular among immigrant populations who left the “old world” in search of a better life. It is also the state nickname of Arkansas.

In the early 1940s, a group of Little Rock (Pulaski County) businessmen known as the Committee of 100 began vigorous efforts to promote economic development and, consequently, stem the tide of outmigration in search of good jobs. Changing the state’s image was central to the group’s efforts. Committee of 100 promotional material referred to Arkansas as “Land of Opportunity,” a phrase more dynamic and perhaps less quaint than the older cognomen. In 1941, the tag phrase appeared for the first time on Arkansas auto license plates. In 1953, the Arkansas General Assembly took note of the committee’s efforts: House Concurrent Resolution 26 explicitly jettisoned “Wonder State,” noting that it did not “command the popular appeal that it once had,” and adopted “The Land of Opportunity” as Arkansas’s new nickname, alluding to a bright outlook for the development of business, industry, and agriculture.

During the 1980s, Arkansas’s outreach to tourists became more aggressive than before, reflecting a maturing understanding of tourism as a growth industry. In the mid-1980s, the Arkansas parks system began promoting Arkansas as “the Natural State” and the nickname proved popular, largely eclipsing the older “Land of Opportunity” in public esteem and currency.
